Applications
Network architects choose the 100G QSFP28 LX4 4x 25G NRZ 1310nm 2km/100m Duplex LC/UPC Module, Cisco for 100G Ethernet, data center interconnect and 5G transport networks: it runs 103.12Gbps (4x 25.78GGbps) over SMF/MMF and reaches 2km@SMF/100m@OM3 MMF. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Standards compliance covers IEEE Std 802.3bm-2015, SFF-8665 Rev 1.9, SFF-8636 Rev 2.10a, SFF-8679 Rev 1.8. The unit works in any equipment with a standard QSFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
Order this product as QSFP-LX4-100G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
